The origin of life on Earth becomes even more fascinating and complex as we peer into the mysterious world of viruses. Said ...

The origin of the first living molecules on our planet has long been debated. However, recent experiments are revealing new ...

Grab-and-go missions to asteroids have provided some of the most scientifically valuable samples since the Apollo ...

The origin of life on Earth has been mulled over by scientists for centuries. We now know that life’s building blocks are RNA, amino acids, and cells. But if life originated from the primordial ooze ...

There is still so much we don’t understand about the origin of life on Earth. The definition of life itself is a source of debate among scientists, but most researchers agree on the fundamental ...

In a new book, astrophysicist Mario Livio describes how the existence of life on Earth can be traced back to an RNA-based “protocell.” The following is an excerpt from Is Earth Exceptional?: The Quest ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched into ...

How did the building blocks of life come together to spawn the first organisms? It’s one of the most longstanding questions in biology — and scientists just got a major clue. In a new study published ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, various diseases and even the origin of life. When you purchase through links ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants. Ten years ago, ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...
